Step1
Download Form 8396 Mortgage Interest Credit from the Internal Revenue Service (IRS) website.
Step2
Complete the information on the form as it is shown on your income tax return. Put the name of the issuer of the MCC, certificate number and the issue date in the applicable sections.
Step3
Enter the interest on the certified mortgage amount in Line 1 and the certified credit rate on Line 2. The credit rate cannot be less than 10 percent or more than 50 percent and it will not be the same as the interest rate on your home mortgage.
Step4
Refer to the Form 8396 instructions for the amount to enter on Line 3 if Line 2 rate is more than 20 percent or you refinanced your mortgage. Otherwise, multiply Line 1 by Line 2 and enter the amount on Line 3.
Step5
Reduce your home mortgage interest deduction on Schedule A or F of tax return Form 1040 by the amount on Line 3.
Step6
Add any credit carry-forwards from prior years and compute the current year mortgage interest credit which will be entered on Line 54 of your Form 1040 tax return. If part of the credit is not currently usable, show those amounts of excess mortgage interest credit as carry-forwards to the subsequent year.
